Transfer news: the use of a simple method allows the various sensitization steps in Eu(III) -containing complexes to be deciphered. Incorporation of an increasing number of electron-withdrawing fluorine atoms on the rigid and electronically tunable phenyl spacer between two tridentate binding units (see picture, red O, dark blue N) affects the quantum yield, intersystem crossing, and energy-transfer processes in a rational way.

1.4% External Quantum Efficiency 988 nm Light Emitting Diode Based on Tin-Lead Halide Perovskite.

Adv Mater

Zernike Institute for Advanced Materials, University of Groningen, Nijenborgh 3, Groningen, 9747 AG, The Netherlands.

In recent years, metal halide perovskite-based light-emitting diodes (LEDs) have garnered significant attention as they display high quantum efficiency, good spectral tunability, and are expected to have low processing costs. When the peak emission wavelength is beyond 900 nm the interest is even higher because of the critical importance of this wavelength for biomedical imaging, night vision, and sensing. However, many challenges persist in fabricating these high-performance NIR LEDs, particularly for wavelengths above 950 nm, which appear to be limited by low radiance and poor stability.

Article Synopsis
  • - This study explores the levels and geographical differences of contaminants found in house dust across Europe, identifying over 1200 anthropogenic compounds using advanced techniques like mass spectrometry and suspect screening.
  • - The research indicates that contaminant concentrations vary less than threefold within Europe, showing similarities with North American dust due to shared consumer products and materials.
  • - It highlights geographical patterns, revealing that certain contaminants increased from north to south (like PAHs and chlorinated paraffins), whereas others, like biocides, decreased; it also emphasizes a significant risk from older, restricted contaminants, like DEHP and PCBs, despite limited toxicity data available for newer compounds.

Article Synopsis
  • The study demonstrated the ability of various crude plant peroxidases, particularly horseradish root (HRP) and pumpkin skin (PKS), to degrade mono- and polyfluorinated phenolic compounds effective for environmental cleanup.
  • HRP showed decreased activity with more fluorinated substrates due to steric hindrance, while PKS maintained higher degradation rates, suggesting its larger active site allows for better interaction with these compounds.
  • The successful library screening method identified high-activity samples, indicating its potential use for discovering new catalysts for the degradation of other fluorinated compounds in the quest for environmentally friendly biocatalytic solutions.

The incorporation of fluorine into amino acids is an important strategy to produce tailored building blocks with unique properties for peptide-based materials. Phenylalanine is frequently modified due to its role in cation-π interactions and the formation of amyloid fibres. Previous studies have utilized gas-phase vibrational spectroscopy to study interactions between canonical amino acids.

Constructing perfluorinated UiO-67 for enrichment of polycyclic aromatic hydrocarbons in seawater and seabed sediments.

J Chromatogr A

November 2024

Henan International Joint Laboratory of Medicinal Plants Utilization, College of Chemistry and Molecular Sciences, Henan University, Kaifeng 475004, Henan, China. Electronic address:

To investigate the ocean contamination caused by polycyclic aromatic hydrocarbons (PAHs), UiO-67/perfluorooctanoic acid (UiO-67/PFOA) was synthesized through solvent-assisted ligand incorporation method. The UiO-67/PFOA was then served as an adsorbent in headspace solid-phase microextraction (HS-SPME) technology for collecting and concentrating trace PAHs. The addition of the PFOA improved the hydrophobicity and stability of the UiO-67/PFOA coating, and the C-F functional group in UiO-67/PFOA could form the pseudo hydrogen bonding with the CH on the benzene ring of PAHs, which endowed the UiO-67/PFOA with 1.
